Bumper made of Polyurethan with incorporated 3M™ Glass Bubbles

As additives to polypropylene and polyamide in demanding injection moulding applications, the Glass Bubbles allow for optimised plastic formulations with even lower density without making sacrifices in terms of durability or other physical properties. The product, which was specially developed for compounding and injection moulding processes in the plastics industry, boasts an isostatic compression resistance of over 1,100 bar (16,000 psi).

At a density of just 0.46 g/cm3, these innovative spheres
can help reduce the weight of plastic systems, depending on
fill level and formulation, by up to 18 percent. The lower weight is complemented by improved productivity: as the Glass Bubbles are hollow, less molten polymer needs to be cooled. This means that cycle times are shortened, by up to 25 percent. Alongside this, the dimensional stability of the components is improved, which results in fewer deformations and thus less waste.
